Two management alternatives for radioactive scrap metal were evaluated : (1) recycling and reuse, and (2) disposal and replacement.
The human health risks, environmental impacts, and sociopolitical issues potentially associated with these alternatives were assessed in an international context.
For each alternative, the health risks from workplace and transportation accidents are greater in magnitude than the risks from potential exposure to radioactive materials or chemicals.
The nonradiological risks are at least twice as high for disposal and replacement as they are for recycling, with the result that recycling has lower health risks overall.
Environmental impacts from disposal and replacement of scrap metals are likely to be orders of magnitude higher than those for recycling.
This is true of effects on land, water, and air quality, as well as for mineral and energy resources.
In addition to risks and costs, issues affecting the choice between radioactive scrap metal management alternatives include low-level waste disposal site availability, public acceptability of recycling, potential impacts on metal markets, impacts of radioactivity on sensitive industrial uses of metal, and international equity issues.
